Ignition coil device

An ignition coil device comprising:

• a core inside a housing, the core having a lower voltage primary winding and a higher voltage secondary winding, each of the primary winding and the secondary winding being wound onto a corresponding spool surrounding the core;
• a heatsink in operative contact with the core, the heatsink being in fluid communication with the outside of the housing;
• an ignition circuit located inside the housing, the ignition circuit comprising:
• a ground terminal extending from the outside of the housing to the inside of the housing, the terminal being operatively connected to a first transistor terminal;
• a signal terminal extending from the outside of the housing to the inside of the housing, the signal terminal being operatively connected to a second transistor terminal by a capacitor;
• a power supply terminal extending from the outside of the housing to the inside of the housing, the power supply terminal being operatively connected to one end of the primary winding and to one end of the secondary winding by a reverse biased diode, another end of the primary winding being connected to a third transistor terminal;
• and
• another end of the secondary winding being operatively connected to a high voltage link block located inside the housing, the high voltage link block being operatively connected to a high voltage conductor located inside the housing;
• and
• the high voltage conductor being operatively connected to a noise suppression resistor extending from the inside of the housing to the outside of the housing.
